本文用固体~（13）C NMR研究了N-叔丁基-2-苯并噻唑次磺酰胺在炭黑存在和不存在下对天然橡胶的加速硫化反应。炭黑填料除了在硫化和稳定方面具有公认的作用外，还对硫化化学有影响。基本的网络结构的形成被修改到一定程度，从聚到单硫化物结构的交联脱硫在炭黑的存在下在固化中较早发生。未检测到主链断裂或双键迁移。
Abstract Solid state C-13 NMR has been used to compare the chemistry of accelerated vulcanization of natural rubber using N-t-butyl-2-benzothiazole sulfenamide in the presence and absence of carbon black. The carbon black filler has an influence on the vulcanization chemistry in addition to its accepted role in reinforcment and stabilization. The basic network structure formation is modified to the extent that crosslink desulfurization from poly to monosulflde structures occurs earlier in the cure in the presence of carbon black. No main chain scission or double bond migration was detected.
